!CAUTION
►Switch off power supply before installing or connecting the device. Failure to observe this
may result in destruction of parts of the electronics.
►When installing Ex-approved devices in a hazardous area, please take special note of the
instructions and connection schematics in the respective Ex documentation added to these

required.
►Do not occupy the display connection. An incorrect connection can destroy the electronics.
For wiring a mounted head transmitter, proceed as follows:
1. Open the cable gland and the housing cover on the terminal head or the field housing.
2. Feed the cables through the opening in the cable gland.
3. Connect the cables as shown in (® ä 11). If the head transmitter is fitted with spring
terminals, pay particular attention to the information in the "Connecting to spring
terminals" section .
4. Retighten the cable gland and close the housing cover.
In order to avoid connection errors always take note of the hints given in the section connection
check!
